Eat a variety of foods

To obtain the nutrients and other substances needed for good health, vary the
foods you eat

Foods contain combinations of nutrients and other healthful
substances. No single food can supply all nutrients in the amounts you need. For
example, oranges provide vitamin C but no vitamin B12; cheese provides vitamin
B12 but no vitamin C. To make sure you get all of the nutrients and other
substances needed for health, choose the recommended number of daily servings
from each of the five major food groups displayed in the Food Guide Pyramid
(figure 1).

Use foods from the base of the Food Guide Pyramid as the foundation of your
meals

Americans do choose a wide variety of foods. However, people
often choose higher or lower amounts from some food groups than suggested in the
Food Guide Pyramid. The Pyramid shows that foods from the grain products group,
along with vegetables and fruits, are the basis of healthful diets. Enjoy meals
that have rice, pasta, potatoes, or bread at the center of the plate,
accompanied by other vegetables and fruit, and lean and low-fat foods from the
other groups. Limit fats and sugars added in food preparation and at the table.
Compare the recommended number of servings in box 1 with
what you usually eat.

What counts as a "serving"?

Seebox 2 for suggested serving
sizes in the Food Guide Pyramid food groups. Notice that some of the serving
sizes are smaller than what you might usually eat. For example, many people eat
a cup or more of pasta in a meal, which equals two or more servings. So, it is
easy to eat the number of servings recommended.

Choose different foods within each food group

You can achieve a healthful, nutritious eating pattern with many combinations of
foods from the five major food groups. Choosing a variety of foods within and
across food groups improves dietary patterns because foods within the same group
have different combinations of nutrients and other beneficial substances. For
example, some vegetables and fruits are good sources of vitamin C or vitamin A,
while others are high in folate; still others
are good sources of calcium or iron. Choosing a variety of foods within each
group also helps to make your meals more interesting from day to day.

What about vegetarian diets?

Some Americans eat vegetarian diets for reasons of culture, belief, or health.
Most vegetarians eat milk products and eggs, and as a group, these
lacto-ovo-vegetarians enjoy excellent health. Vegetarian diets are consistent
with the Dietary Guidelines for Americans and can meet Recommended
Dietary Allowances for nutrients. You can get enough protein from a vegetarian
diet as long as the variety and amounts of foods consumed are adequate. Meat,
fish, and poultry are major contributors of iron, zinc, and B vitamins in most
American diets, and vegetarians should pay special attention to these nutrients.

Vegans eat only food of plant origin. Because animal products are the only food
sources of vitamin B12, vegans must supplement their diets with a source of this
vitamin. In addition, vegan diets, particularly those of children, require care
to ensure adequacy of vitamin D and calcium, which most Americans obtain from
milk products.

Foods vary in their amounts of calories and nutrients

Some foods such as grain products, vegetables, and fruits have many nutrients
and other healthful substances but are relatively low in calories. Fat and
alcohol are high in calories. Foods high in both sugars and fat contain many
calories but often are low in vitamins, minerals, or fiber.

People who do not need many calories or who must restrict their food intake need
to choose nutrient-rich foods from the five major food groups with special care.
They should obtain most of their calories from foods that contain a high
proportion of essential nutrients and fiber.

Growing children, teenage girls, and women have higher needs for some nutrients

Manywomen and adolescent girls need to
eat more calcium-rich foods to get the calcium needed for healthy bones
throughout life. By selecting low fat or fat-free milk products and other low
fat
calcium sources, they can obtain adequate calcium and keep fat intake from being
too high (box 3). Young children, teenage girls, and
women of childbearing age should also eat enough iron-rich foods, such as lean
meats and whole-grain or enriched white bread, to keep the body's iron stores at
adequate levels (box 4).

Enriched and fortified foods have essential nutrients added to them

National policy requires that specified amounts of nutrients
be added to enrich some foods. For example, enriched flour and bread contain
added thiamin, riboflavin, niacin, and iron; skim milk, lowfat milk, and
margarine are usually enriched with vitamin A; and milk is usually enriched with
vitamin D. Fortified foods may have one or several nutrients added in extra
amounts. The number and quantity of nutrients added vary among products.
Fortified foods may be useful for meeting special dietary needs. Read the
ingredient list to know which nutrients are added to foods (figure 2). How these foods fit into your total diet will
depend on the amounts you eat and the other foods you consume.

Where do vitamin, mineral, and fiber supplements fit in?

Supplements of vitamins, minerals, or fiber also may help to meet special
nutritional needs. However, supplements do not supply all of the nutrients and
other substances present in foods that are important to health. Supplements of
some nutrients taken regularly in large amounts are harmful. Daily vitamin and
mineral supplements at or below the Recommended Dietary Allowances are
considered safe, but are usually not needed by people who eat the variety of
foods depicted in the Food Guide Pyramid.

Sometimes supplements are needed to meet specific nutrient requirements. For
example, older people and others with little exposure to sunlight may need a
vitamin D supplement. Women of childbearing age may reduce the risk of certain
birth defects by consuming folate-rich foods or folic acid supplements. Iron
supplements are recommended for pregnant women. However, because foods contain
many nutrients and other substances that promote health, the use of supplements
cannot substitute for proper food choices.

ADVICE FOR TODAY

Enjoy eating a variety of foods. Get the many nutrients your body needs by
choosing among the varied foods you enjoy from these groups: grain products,
vegetables, fruits, milk and milk products, protein-rich plant foods (beans,
nuts), and protein-rich animal foods (lean meat, poultry, fish, and eggs).
Remember to choose lean and low fat foods and beverages most often. Many foods
you eat contain servings from more than one food group. For example, soups and
stews may contain meat, beans, noodles, and vegetables.
